One member of the Greens says the caucus hasn't met for discussion on whether to invoke waka-jumping laws against Darleen Tana.

Tana has left the party, but if she won't quit Parliament, the Greens can only replace her in their MP count if the Speaker removes her, an action the Party has historically opposed.

Its report found Tana likely knew about alleged exploitation at her husband's business - E Cycles NZ - which is now in liquidation because of poor sales.

Ricardo Menendez-March says he hasn't considered putting the issue to members at the AGM.

He says it's up to members if they want to discuss it - but the right thing for Tana to do is resign.
